Survey and define
Confirm objectives, risk, system category or grade, interfaces, existing condition, constraints and responsibilities.
Commercial fire and security systems
Installed properly. Maintained to stay dependable.
Design support, installation, programming, commissioning, planned maintenance, fault-finding and remedial works for fire alarms, intruder alarms, access control, CCTV and lockdown systems.
One accountable technical team
From site survey to documented handover.
Every project starts with the building risk, operational requirement and agreed design basis. The scope is then carried through installation, configuration, verification, user training and maintainable records.
Install and configure
Complete agreed containment, cabling, devices, control equipment, network configuration, labelling and cause-and-effect programming.
Test and commission
Verify device operation, coverage, audibility or intelligibility, signalling, interfaces, fault monitoring, recovery and user controls.
Handover and maintain
Provide certificates, as-fitted information, configuration records, training, defect status and a planned maintenance regime.
Systems covered
Installation and maintenance matched to the actual risk.
We do not force every building into the same specification. Equipment, system extent, resilience, monitoring and service frequency are agreed against the fire strategy, security risk assessment, operations and applicable requirements.
Life safety
Fire detection and alarm
Conventional, addressable and networked systems; aspirating smoke detection; manual call points; sounders and visual alarm devices; fire and fault signalling; and agreed interfaces to doors, lifts, plant, suppression, smoke control and building systems.
- New systems, extensions, replacement and phased upgrades
- Cause-and-effect programming and interface testing
- Routine inspection and servicing, fault-finding and remedials
- Logbooks, certificates, zone plans and as-fitted records
Property and people
Intruder and hold-up alarms
Risk-based detection, control equipment, warning devices and monitored signalling, designed around the required security grade, environmental class, insurer requirements and intended police or keyholder response.
- Wired, wireless and hybrid systems
- Confirmed alarm configuration where required
- Alarm transmission and ARC integration
- Preventive maintenance, false-alarm investigation and repairs
Secure movement
Access control and door systems
Electronic access control, readers, credentials, controllers, monitored doors, interlocks and time profiles, with explicit treatment of emergency release, fire-alarm response, accessibility and safe escape.
- Single-door to networked enterprise systems
- Fail-safe or fail-secure operation defined by risk and door function
- Fire release, emergency override and recovery testing
- Door hardware, permissions, event logs and maintenance records
Video surveillance
CCTV and VSS
Video surveillance designed from an operational requirement: what must be observed, detected, recognised or identified; under which lighting and environmental conditions; by whom; and for how long recordings are lawfully retained.
- IP cameras, recording, networks, displays and remote access
- Coverage, image quality, storage and time synchronisation testing
- Privacy masking, access permissions and audit controls
- Cleaning, health checks, firmware planning and evidence export tests
Protective security
Lockdown and emergency communication
Risk-led systems that support evacuation, invacuation, lockdown and communication procedures without creating an unmanaged conflict with fire precautions or safe egress. A lockdown system is only effective when the technology, authority to activate, messages, staff actions, overrides and recovery plan are tested together.
- Manual and automated initiation, zoning and priority controls
- Audible, voice, visual and digital communication pathways
- Door, gate, lift and control-room interfaces where appropriate
- Scenario testing, backup communications, reset and post-event recovery
Maintenance built around evidence
Know what was tested, what failed and what happens next.
A service visit is more than a signature. We record the agreed test scope, results, limitations, outstanding defects, recommendations and any follow-on work needed to restore the required performance.
Preventive servicing
Scheduled inspection, functional testing, cleaning, battery and power checks, event-log review, signalling checks and user feedback.
Faults and repairs
Structured diagnosis, temporary-risk communication, component replacement, configuration correction and retesting.
Extensions and upgrades
Survey, compatibility review, change control, installation, commissioning and updated as-fitted information.
Service reporting
Clear records of devices or functions tested, defects, impairment, exclusions, actions, owners and recommended timescales.
Important: maintenance frequency is set by the applicable standard, risk assessment, system condition, manufacturer, insurer, contract and enforcing authority. Fire alarm inspection and servicing under BS 5839-1:2025 must be carried out at intervals not exceeding six months; higher-risk or fault-prone systems may need more frequent attendance.
UK compliance framework
Legislation, standards and guidance.
Legislation creates duties. British Standards and recognised guidance normally provide accepted technical routes to meet the relevant performance objective, but they are not automatically law unless required by legislation, approval, contract, insurer or specification.
Project-specific basis. The applicable edition and requirements are confirmed when the work is scoped. Building type, jurisdiction, fire strategy, risk assessment, planning or building-control approval, insurer and existing certification may add or change requirements.
Fire detection and alarmLaw, design, installation and maintenance
Principal legislation
- Regulatory Reform (Fire Safety) Order 2005, as amended, for England and Wales. Article 17 requires relevant fire precautions to be maintained in an efficient state, efficient working order and good repair.
- Fire Safety Act 2021 and, where applicable, the Fire Safety (England) Regulations 2022.
- Fire (Scotland) Act 2005 and Fire Safety (Scotland) Regulations 2006; or the Fire and Rescue Services (Northern Ireland) Order 2006 and Fire Safety Regulations (Northern Ireland) 2010.
- Building Regulations 2010 and the applicable national technical guidance for new work or material alterations; the Building Safety Act 2022 and associated dutyholder or information requirements where in scope.

Intruder and hold-up alarmsGrading, confirmation, signalling and police response
Legal and contractual context
There is no single UK Act that makes an intruder alarm mandatory for every commercial premises. The required protection is normally driven by risk assessment, contract, insurer, licensing conditions and, for monitored systems, alarm-receiving-centre and police-response requirements. General work and electrical safety duties still apply.
Key technical references
PD 6662:2017 and the BS EN 50131 series; DD CLC/TS 50131-7:2010 for application, commissioning and maintenance; BS 8243:2021 where confirmed alarms and police response are intended; the BS EN 50136 series and PD 6669:2017 for alarm transmission; BS 9518:2021 for signal processing by an ARC; and the current NPCC requirements and response policy where police response is required.
Police response, a Unique Reference Number and insurer acceptance can depend on an appropriately recognised installer, monitoring route and certification scheme. These requirements are confirmed before VectorShield accepts that part of a scope.
Access control and controlled doorsSecurity, safe egress, accessibility and personal data
Principal legislation
Relevant duties can arise under the fire-safety legislation for the premises, building regulations, the Equality Act 2010, and data-protection legislation where credentials, photographs, vehicle data or biometrics identify people. Security controls must not create an unjustified obstruction or unmanaged failure mode on an escape route.
Key technical references
BS EN 60839-11-1:2013 for system and component requirements; BS EN 60839-11-2:2015 for planning, installation, commissioning, maintenance and documentation; BS EN 13637:2015 for electrically controlled exit systems; and BS 7273-4:2015+A2:2023 where the fire alarm actuates door-release mechanisms.
CCTV and video surveillanceOperational requirement, image performance and privacy
Principal legislation and regulatory guidance
The Data Protection Act 2018, UK GDPR and amendments made by the Data (Use and Access) Act 2025 govern personal-data processing. The system owner remains responsible for a lawful purpose, necessity and proportionality, transparency, access controls, retention, disclosure, security and data-subject rights. Follow current ICO video-surveillance guidance.
The Protection of Freedoms Act 2012 and Surveillance Camera Code of Practice apply directly to specified relevant authorities in England and Wales and provide useful principles more widely. The Private Security Industry Act 2001 and SIA licensing can apply to contracted public-space surveillance activities.
Key technical references
BS EN IEC 62676-4:2025 for planning, design, installation, testing, commissioning and maintenance of video surveillance systems, supported by the wider BS EN 62676 series; and BS 7958:2015 for management and operation in controlled environments.
Lockdown and emergency communicationPreparedness, life safety and tested procedures
Principal legislation and official guidance
The Health and Safety at Work etc. Act 1974, Management of Health and Safety at Work Regulations 1999, applicable fire-safety law and the Equality Act 2010 inform the risk assessment, emergency plan, communication and safe operation of lockdown measures.
The Terrorism (Protection of Premises) Act 2025, commonly known as Martyn's Law, includes evacuation, invacuation, lockdown and communication within public-protection procedures for qualifying premises and events. As at 3 September 2026, its substantive requirements have not yet commenced, so they are not yet in force. Organisations can use the Home Office statutory guidance to prepare.
System design and testing should also follow current ProtectUK lockdown guidance and relevant NPSA guidance. BS EN 50849:2017 applies where a sound system is used for non-fire emergency purposes; BS 5839-8:2023 applies where the system is a fire voice-alarm system. There is no single British Standard that by itself defines every lockdown system.
All installation and maintenance workCompetence, safe work and electrical installation
Work is planned with regard to the Health and Safety at Work etc. Act 1974, Management of Health and Safety at Work Regulations 1999, Electricity at Work Regulations 1989, and Construction (Design and Management) Regulations 2015 where construction work is involved.
Relevant electrical work follows BS 7671:2018+A4:2026, including applicable transition arrangements, alongside equipment manufacturers' instructions. Product selection and installation also consider applicable product-safety, construction-product, electromagnetic-compatibility and radio-equipment requirements.
Clear roles and evidence
What you receive.
Deliverables are matched to the system, contract and project stage, with variations and exclusions recorded rather than hidden.
Agreed design basisRisk, category or grade, operational requirement, system boundaries, interfaces, departures and responsibilities.
Installation and commissioning recordsTest results, device schedules, configuration, cause-and-effect, signalling and interface evidence.
Handover informationCertificates, as-fitted drawings, logbooks, operating information, training and outstanding-defect status.
Maintenance reportScope completed, limitations, faults, impairments, remedials, recommendations and next attendance.
Installation and independent assurance are separate appointments.
VectorShield can install, commission and maintain a system, and can also provide consultancy and assurance services. Where a client, contract, insurer or approval body requires independent third-party verification, the independence requirement will be declared and the roles kept appropriately separate. No service transfers the legal duties of the responsible person, employer, accountable person, client, designer, principal designer, contractor, operator or system owner.
Frequently asked
Before we attend.
Can you take over an existing system?
Yes, subject to an initial survey and access to the equipment, software, passwords, records and manufacturer support needed to work safely and competently. We will identify limitations or unsupported equipment before agreeing the maintenance basis.
How often should a commercial fire alarm be serviced?
Under BS 5839-1:2025, the interval between successive inspection and servicing visits should not exceed six months. The fire risk assessment, system condition, premises risk, insurer or enforcing authority may require a shorter interval.
Do you provide emergency call-out cover?
Call-out response, hours, geographic coverage and target attendance are agreed in the maintenance proposal. We do not advertise a guaranteed response that has not been contractually resourced.
Can you certify police-response intruder alarms?
Police response and insurer acceptance can depend on recognised certification, monitoring and installer-scheme requirements. We confirm the exact requirement before accepting the work and will not imply an approval that is outside our appointment.
